Was finally able to take the Sling out yesterday...after having the Mesh Windscreen installed for more than 2 weeks. Verdict...IT WORKS! Not in an over the top, stop all wind, kind of way. It is just enough to stop the wind from whipping in from behind. I would venture to say that if you had an F4 windshield or even the stock windshield from the SL for 2015 on (not including the ripper), that this would be the perfect product to slow down the air turbulence in the cabin. I say not the Ripper because they have the same middle section that allows air to flow in under the windshield like the Madstad and the new Twist Dynamics windshields. That air still comes in from under the windshield and you will always notice it.
Having this with the Madstad, was interesting. It almost created a little bit of rear push. As weird as it sounds, it felt like the Windscreen was acting like a sail. After about 90 MPH, it felt like I was getting a small push from the rear of the Slingshot and it was easier to break 100 MPH, 110 MPH, and even 120 MPH...and maybe a little more...will not confirm nor deny at what speeds I tested this product to. With that being said, I actually thought it would create drag and catch bugs. It didn't feel like it or show any signs of doing either.
At this price point...this is a must have product for everyone. Very happy with it @lrobbi!
Your absolutely right @Br4hm4 that little bit of rear push you feel is real. it is the result of cleaning up the parasitic drag created by the aerodynamics of the Slingshot. Without getting to technical here, let me explain , the windshield creates a low pressure area behind it when speed increases and the airflow is directed up over the cockpit area. The laws of physics say air pressure will always try to equalize in a given space. So as the slingshot speeds up and the low pressure area increases behind the windshield air is drawn in through the path of least resistance from the back of the slingshot to try and equalize that lower pressure area . Wind Restrictors or mesh screens simply interfere with the speed of the airflow from the back trying to enter the cockpit. hence a calmer cockpit as the airflow from the back is slowed down. In the high speed auto convertibles a female passengers longer hair will clearly fly forward when up to speed NOT BEHIND HER AS ONE WOULD EXPECT . this is the forward draw of air coming in from the back that all high end convertibles like the 2018 BMW i8 and F4 Jaquars now greatly reduce with the introduction of rear windscreens.
That parasitic drag created as the airflow recirculates back in definitely reduces efficiencies and hampers performance slightly.
Here is a simple airflow diagram over a F4 series Jaquar , note the small but significant enough, elimination of air being drawn back into the cockpit after a wind restriction device is installed. this is a reduction of parasitic drag which slows all vehicles down , hence a small performance gain can be noticed when installing an effective wind restrictor or mesh screen as R-Shot so was so keen to introduce and manufacture for Slingshots.
It is similar to reducing the parasitic drag the transportation industry is quickly learning about as we see more and more boat tails on the backs of transport trailers going down the road, in that industry it is well documented adding the extra length and weight of the boat tail actually increases efficiencies (performance) by 1% by simply reducing the drag of the airflow .
For all new orders effective tomorrow you can expect a shipping date of 15 May. Thanks again everyone
